CVM2072SM4SS General Electric Microwave - Instructions

Trouble shot first by removing the digital read out face plate panel, lifting it up and out. Found the thermostat housed on the bottom section (found a picture of what I was looking for). It had two connectors. Removed the connectors and noticed that the one looked burnt/melted that was on the thermostat. Took paper clip, connected it with the wires to bypass the thermostat. Plugged in the microwave and power returned. Yes! Ordered thermostat part and changed it out. The new part didn't have a piece that fit exactly into the floor of the microwave so I just made sure it was secure to the bottom. It is only attached by 1 small screw. Fixed!

Microwave would not turn on--No lights--Nothing worked 1. Removed screws from back and side and pull off microwave cover. Be careful! There HIGH voltage back there due to a large capacitor that stores power. This capacitor is charged up even with Microwave unplugged. I checked the fuse located on top back part of Microwave. A lot of the time this is the problem but this time the fuse was good. I used an Ohm meter to check to see if there was an open circuit in one of the Thermostats. There are two of them in the Microwave. The Thermostats are about the size of a dime. One is located on the top right side and the other is on the top left side. One of them was bad. I ordered a new Thermostat. It arrived in just 2 days. I installed it and the Microwave was repaired and working great.

Had to take the MW off the wall, remove the cover, and find the magnetron. Issue was the HV-capacitor. Had to remove the diode and capacitor to discharge the capacitor safely. Crackle-Bang! Then put it back before toying with the HV-transformer in order to get the magnetron out. Took a little under two hours to get it back on the wall and a lot of cajones when monkeying around the chassis removing the capacitor. Not a job for most everyone as this was a potentially high-shock repair due to the voltage and micro-farads held in that capacitor. Hardest part was getting the magnetron to drop out past the HV-transformer. Also, the thermostat had to be removed from the magnetron and re attached to the new one. Fiddly delicate job, not for the clumsy or faint of heart.
